I need to handle every route with rtpengine depending websocket it or not
(branch_route[1] at my first message). Lookup keep handling close with
branch route. So I can not understand how send to branch_route with lookup
function.

Hello,
r-uri itself is a branch. Practically, an append_branch() in request_route
is adding a new destination in addition to r-uri address.
Maybe you can explain why lookup("location") is not working for you, as it
is updates the branch for r-uri as well as adds the other contacts as extra
branches.
You may want to set a branch flag when processing the REGISTER to know
that it is a websocket. Then, you can test the same branch flag in
branch_route to discover if the destination is over websocket or not.
Cheers,
Daniel

I hav an issue with append branches to branch route when I need fork call
to one endpoint woth different destionations.
I use my own algorithm for call to this devices because with
lookup("location") I can not use RTPENGINE for different types of endpoints
(web endoints and standart UDP endpoints)
My alg is here:
{
sql_query("ca", "select contact from location where
username='$tU'", "ra");
xlog("L_INFO","rows: $dbr(ra=>rows) cols:
$dbr(ra=>cols)\n");
if($dbr(ra=>rows)>0){
$var(i)=0;
while($var(i)<$dbr(ra=>rows)){
xlog("L_INFO","SQL query return contact
{$dbr(ra=>[$var(i),0])} for {$tU} at step {$var(i)}\n");
if ($dbr(ra=>[$var(i),0])=~"transport=ws"){
xlog("L_INFO", "This is a Websocket call to
endpoint");
sql_pvquery("ca", "select received from location
where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)");
$du=$var(recieved);
xlog("L_INFO","SQL query return recieved
{$var(recieved)} for {$tU}. Destination is {$du}\n");
append_branch("sip:$tU@$(du{s.select,1,:})");
}
else
{
xlog("L_INFO", "This is a classic UDP call to
endpoint");
$var(recieved)='';
sql_pvquery("ca", "select received from location
where contact='$dbr(ra=>[$var(i),0])'","$var(recieved)");
xlog("L_INFO", "SQL query return RECIEVED
{$var(recieved)}");
if ($var(recieved)==0){
xlog("L_INFO", "Recieved string is
EMPTY");
$du="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@});
}
else {
xlog("L_INFO", "Recieved string is
{$var(recieved)}");
$du=$var(recieved);
}
$var(UDP_contact)="sip:"+$(dbr(ra=>[$var(i),0]){s.select,1,@});
append_branch("sip:$tU@$(du{s.select,1,:})");
xlog("L_INFO","Classic Destination URI is
{$dbr(ra=>[$var(i),0])} for {$tU}}. Destination is {$du}\n");
}
$var(i) = $var(i) + 1;
}
}
else{
exit;
}
t_on_branch("1");
return;
}
}
}
branch_route[1]{
if($du=~"transport=ws"){
xlog("L_INFO","Websocket Branch is {$du} for {$tU}\n");
rtpengine_manage("internal extenal force trust-address replace-origin
replace-session-connection ICE=force RTP/SAVPF");
t_on_reply("REPLY_FROM_WS");
}
else{
xlog("L_INFO","UDP Branch is {$du)} for {$tU}\n");
rtpengine_manage("replace-origin replace-session-connection ICE=remove
RTP/AVP");
t_on_reply("MANAGE_CLASSIC_REPLY");
}
}
So as you see I choose array of devices and then set its to branches.
At the kamailio console I see output
This is output of alg that above.
I have 3 devices: 2 websocket devices and 1 udp
But when you look at dump where rtpengine make changes with packets you
can see that it runs for 4 devices and 1 and 4 devices is the same.
You can see start of every branch from words of log "Websocket Branch is"
or "UDP Branch is"
So this bug gives a mistake because some of hardphones can not handlie
double INVITE and kamilio response for this devices cancel with 200 cause
because hardphone set 482 reply to kamialio.
(you can see it reply at the log)
